APOD published September 17, 1995. Credit: Royal Observatory Edinburgh, Anglo-Australian Observatory, and AURA Explanation: Almost every object in the above photograph is a galaxy. The Coma Cluster of galaxies pictured is a dense cluster containing many thousands of galaxies. Many of these galaxies contain as many stars as our own Milky Way Galaxy. Although nearby when compared to most other clusters, light from the Coma Cluster still takes hundreds of millions of years to reach us. In fact, the Coma Cluster is so big it takes light millions of years just to go from one side to the other! This picture was created at the WWW site Skyview, a "virtual observatory" where it is possible to view any part of the sky in wavelengths from radio to gamma-ray. Tomorrow's picture: The Large Cloud of Magellan | Archive | Glossary | Education | About APOD | Astronomy Picture of the Day (TM) is created and copyrighted in 1995 by Robert Nemiroff and Jerry Bonnell who are solely responsible for its content..
